SPECIFICATION forming part of Letters Patent No.'"29e,5eo, dated February 12, 1884. Application filed October 22, 1833. (No model.)

vapor-fuel apparatus to locomotives, boilers,

and other furnaces. The construction shown 1s particularly adapted to'locomotives; but it will be obvious from theaccompanying description that it is equally applicable to any boiler or furnace.

My invention consists of constructions and combinations, all as will hereinafter be described in the specification and pointed out in the claims, reference being had to the accompanying drawings, in which-- Figure 1 represents a longitudinal section of a locomotive having the vapor-fuel apparatus adapted thereto, Fig. 2, a vertical section on line 1 1 of Fig. 3, the retort andpipe E being partly in section, Fig. 3, a vertical section on line'2 2, Fig. 2, showing the retort partially in section; Fig. 4, a Vertical section through the jackets and part of the oil-vapor izer inclosed therein; Fig. 5, a horizontal section on line 3 3, Fig. 4; Fig. 6, a horizontal section on line 4 4, Figs. 2 andS; Fig. 7, a horizontal section 011 line 5 5, Figs. 2a11d 3; Fig. 8,

. a horizontal section on line6 6, Fig. 3, Fig. 9,

a detail showing part of the dome and part of the retort in section; Fig. 10, avertical section of a furnace on line 7 7, Fig. 12; Fig. 11, a vertical section on line 8 8, Fig. 12; Fig. 12, a horizontal section on line 9 9, Figs. 10and 11; Fig. 13, a vertical section of the retort and part of the vaporizer; Fig. 14, a horizontal section on line 10 10, Fig. 13; Fig. 15, a detail view of the burner and its inclosing-case.

A represents the boiler-furnace; B, the firebox; 0, the retort, and D the burner; F, the

steam-dome. The fire-box B is provided with The upper part of the firebox is provided with an arch, B, which forms a fire space for the burner D. In the center of this arch is of combustion into a chamber, B, which is the ends, so that the products of combustion will be deflected against the walls before escaping. Above this arch is a chamber, B, havingia large central aperture, B for the bottom of the retort O, and fines b for the escape of the products of combustion into the casing, which is arranged as follows:

, Immediately next to the firebox B is a space,

Inclosing this is a second jacket, forming a fine, 6, communicating with the chamber B by the flues b passing the superheater b, and

flue B into which the fire-tubes B open.

Between the fiues B and b isasteam-spaoe, b, communicating by part b with the space b. It will be seen that the fines and steam-space inclose the fire-box on all sides, and the steam in superheater bis expanded to such an extent as to put the whole pressure through. its exit-pipe B into the retort O. The outer jacket of the space If is provided with open ings for the ends of steam-pipe 13 and has transverse partitions b which separate the pipes B in pairs, so that the steam will enter the top space, I)", through th'eupper pipes, and escape into the next set'below, and be returned to the space b, and so on until the steam enters the space below the lowermost partition b If desired, the partitions b may be dis pensed with andthe pipes coupled together in the samemanner as the front ends, I), except that the lowermost pipe will open into the space I), as shown in dotted lines, Fig. 2. These pipes 13 are inserted in and 'follow the course of the dues B", as shown in Fig; 1, and receive the steam from dome F by means of pipe B ,which is connected to the upper pipe 13 and terminates within the steam-dome. This dome is attached to an offset, f, on the top of the boiler by means of aflange, f, and bolts fi es shown in Fig. 9. The opening in the top of the boiler is 1 provided with an ansteam to escape from the boiler to the dome.

Bolted to thisflange by a flange, t isacylinan opening, I), for the escape of the products arched by a plate, 13 having openings 12 atb, which I designate as the superheater.

provided with an outlet, b", connecting it with nular flange, z',having perforations. i, for the drical casing, I, which is bolted at its lower end by a flange, F, to the crown-sheet I Suspended from this casing I by a flange, c, is a jacket, 0, which extends through the casing I to the chamber'B. If desired, the jacket may be of such size that there will be an open space extending from the top of chamber B to the flange c, which prevents the gases in chamber B from escaping into the steam-space. The flange c is provided with an inwardlyextending part, 0 provided with a groove, 0, to receive the tongue 0 of flange c on jacket 0 which is suspended in the chamber formed by jacket 0'. (See Figs. 9 and 13.) If desired, a third jacket, 0 may be interposed between jackets G and (J by means of similar flanges, as shown in Fig. 4. The jacket (3 contains the oil-vaporizer O, which is formed as follows:

Attached to the bottom of the jacket in any suitable manner is a tube, 0 having a vertical partition, 0, which divides it into two parts. The tube is made up of sections cemented together, and each section is provided with a plate having a spiral passage. Bods attached to the bottom and top plates hold the parts together. In Fig. 4 the tube is closed at top and bottom, and connected with the steam-space G by pipe 0 of the top plate, 0. The steam admitted into this plate winds its way through the passages and escapes into passage 0*, having partitions c ,\vhich divide the passage into several smaller passages, and are formed between the inlet and outlet of plates 0, so that the steam entering the part c of plates 0" will be whirled through the spiral passages and back into the passage 0* below the partition. The bottom plate, 0 differs from the others in that'the steam is drawn from passage c and discharged into passage 0. Below this'plate is a perforated plate, a, connecting with passage 0 at 0 and discharging steam upwardly in the retort O. Beneath each plate is a perforated plate, a", which allows the oil dropped from pipe E to trickle through and meet the incoming steam. The tube 0 shown in Fig. 13 differs "from that shown in Fig. 4 in' that the steam is admitted at the bottom of passage 0 instead of at the top, as shown in Fig. 4. The passage 0* is partitioned off between the inlet and outlet of each plate, and

the outlet of the top plate opens into the passage c, which is closed at its bottom. 1

It will be seen by the foregoing that the superheated steam admitted fromchamber C to the oil-vaporizer is kept constantly on the move until it makes its exit into the vaporforming chamber. The steam admitted to these plate is drawn from the superheatingchamber b by means of pipe B", which passes through the outer jacket, 0 and opens into the space 0. If the intermediate jacket, 0 be used, it is perforated near its top, at c, on the side opposite to that in which the steam enters the end 0" of coil c so that the steam willpass around the jacket 0 to end 0".

suitable point, and passes through the dome and cap 0 and cap 0", if it be used. The vapor-pipe E leads from the mixing-chamberto the fire-box,where it is attached to the burner D. The cylinder steam-supplying pipe E extends from the top of the dome downwardly between the retort and dome and through the boiler in the usual manner.

To the throttle-valve e is attached a rod-E, which is curved to pass around the retort, as

shown in Fig. 6. This curvature of the rod relieves me of the necessity of changing the position of the throttle-valve and the location of the end of the rod in the cab.

If desired, the superheaters around the firebox may be tapped by a pipe, E having a case, 6, at its opposite end to inclose the burner for supplying superheated steam at the point of combustion, as shown in Fig. 15. In front of the burner are placed a series of bricks, 6 arranged in a staggering manner, so as to thoroughly commingle the gas and steam.

The operation ofthe-device is as follows: The pipe B is connected with a boiler in the roundhouse, and steam forced through it into the pipes B from whence it escapes into the superheater 12 through space b and port If. The steam escapes from the superheater to the retort through pipe B leading to the space 0 therein, and having an opening near its upper part, which is connected at 0 to the plate 0. From the plate it passes to the tube and escapes into the retort, as before explained, and is taken off by the vapor-pipe, from which it escapes into the air. \Vhen the parts have become sufficiently hot, oil is admitted to the retort through pipe E, and, dropping upon the heated plates, is turned to vapor, which is commingled with the superheated steam escaping through the perforated plate 0", and the combined steam and vapor taken off by the vaporpipe,which'is now made to communicate with the burner G. Instead of attaching the pipe B to a boiler in the roundhouse, a fire may be started in the firebox B, and as soon as the steam is formed open the cock I) and allow the steam to enter pipe B and pass through the parts as above described. As soon as the parts have become sufficiently heated to vaporize the oil, the fire is withdrawn from firebox B and the door of firebox and ash-pit B closed against the admission of air. The burner D is then started and the heat from the flame thereof is partly confined in the fire-box, so that its walls will become thoroughly heated and superheat the steam in superheater Z). The productions of combustion from firebox B pass through opening I) into B, and are drawn to the ends thereof by the openings 11 through which they escape into chamber B and impinge against the bottom of jacket G. The products of combustion then pass through flues 1) into flue b and heat the incoming steam in space 12, and escape through firebox, and the fuel-pressure is exerted upon 'if it be used down between the the retort by connecting it with the superheater 1) by a pipe, B. Any water of condensation that may be formed in the superheaters b and I) may be drawn off through pipe I).

It will be seen by the foregoing that my retort is placed in such a position as to receive all possible benefit from the different parts of the locomotive, as well as economize space. In appearance a locomotive of the form now in use will not be changed.

In Figs. 10 and 11 I show my device adapted to any ordinary furnace. The steam is forced through pipe 1) into the steam-space I), and through port 1) into superheater b, from whence it escapes into chamber (3 by means of pipe B, which passes through cap 0 and C", jackets, as shown in Fig. 13. l
